U.S. health officials have decided to shorten the recommended quarantine and isolation period from ten days to five for breakthrough cases. The Centers for Disease Control and Prevention's updated guidelines have sparked an avalanche of Twitter memes that satirize and poke fun at the announcement. Many likened the new guidelines to bad dating advice. 'The CDC now recommends ignoring the red flags and texting him anyway' said @relatableafmd. 'The CDC just announced that you actually *can* change him, so keep trying!' joked @hellolanemoore. Others used the snowclone to reference iconic movies like Jurassic Park and Alien. 'The CDC announced that if the spider alien thing that latched onto your face just fell off after you lost consciousness for an unknown amount of time then you're totally fine, you can eat lunch with the rest of the ship' tweeted @bobvids.
